What we hold about you, why, for how long, and what you can ask us to do with it.
E.Y.F. Engineering Your Firm LTD (registered in Cyprus, number ΗΕ 458838, tax identification number 60072173X, based in Limassol, Cyprus) is the controller of the account data described below. Contact: engineeringyourfirm@gmail.com.
For the content you and your team put into workspaces, your organisation is the controller and we act only as its processor, under the data-processing agreement. If you are someone whose details a customer has put into a workspace, please contact that customer first.
| Data | Why | Kept for |
|---|---|---|
| Name and email address | To create your account and let colleagues invite you | Until you delete your account |
| Password (stored only in scrambled form) | To sign you in | Until you change it or delete your account |
| Two-step sign-in key and recovery codes, if you turn it on | To check your sign-in codes | Until you turn it off or delete your account |
| Workspace content | To provide the service | Until you delete it. Deleted content can remain in backup copies for up to 30 days |
| Sign-in and security records (time, internet address, action) | To protect accounts and investigate misuse | 12 months, then deleted automatically |
| Web server logs (internet address, page requested, time) | To keep the service running and stop attacks | Up to 14 days |
| Invitations to a workspace (email address, role) | So the person invited can accept or decline | Until answered, or 14 days |
| Unfinished sign-ups (name, email, scrambled password) | To finish creating the account when you open the emailed link | 48 hours |
| Messages you send us | To answer you | As long as needed to deal with your message |
| Billing records, once paid plans open | To charge for the service and meet tax law | As long as tax law requires |
If your workspace is on the Business plan, its owners can see whether you have two-step sign-in turned on, and a record of who joined, left or changed role in that workspace. They never see your sign-ins or anything you do in other workspaces.
We do not make automated decisions about you that have legal or similar effects, and we do not build profiles of you.
The app sets one cookie, which keeps you signed in for up to 30 days. It also keeps a working copy of your open workspace and your layout choices in your browser's own storage, so you can keep working if the connection drops. Both are needed for the service to work, so no consent banner is shown. We use no advertising or analytics cookies and load nothing from other companies. This website sets no cookies at all.
We do not sell personal data or share it for advertising.
The service and its nightly backups are hosted in the European Union, in Hetzner's data centre in Germany. Further backup copies are kept on our company computer in Cyprus. Your account and workspace data is not transferred outside the European Economic Area. Messages you send us by email are handled by Google, which may process them outside the European Economic Area under the safeguards it provides for EU users.
Under data-protection law you can ask for a copy of your data, have it corrected or deleted, object to or restrict its use, and take it elsewhere. You can download your data and delete your account yourself at any time, under Workspace, Account and team. For anything else, write to engineeringyourfirm@gmail.com; we answer within one month.
You can also complain to a data-protection authority. Ours is the Office of the Commissioner for Personal Data Protection in Cyprus (dataprotection.gov.cy); you may also go to the authority in your own country.
The measures we take are described on the Security and your data page. If a breach of personal data puts people at risk, we will inform the authority within 72 hours of becoming aware of it, and tell the people affected without delay.
Mechanesmos is a tool for work and is not meant for anyone under 18.
If this notice changes in a way that affects you, we will tell you by email before the change takes effect.
